WRENCH.

Application filed July 12, 1922. Serial No. 574,424.

To all whom it may concern Be it known that I, GLAon E. QUIER, a citizenof the United States residing at Princeton, in the county of -arney andState of Oregon, have invented new and useful Improvements in Trenches,of which the following is a specification.

This invention relates to improvements in wrenches and has for itsprincipal object to provide a wrench having a handle with an enlargedtoothed head and a stationary jaw consisting of a pair of plates whichare pivotally connected to said head and a movable jaw comprising atoothed rack bar which is adapted to slide between the plates formingthe stationary jaw and co-engage with the serrated or toothed head ofthe handle.

Another object of the invention is to provide a wrench having a slottedmovable jaw with curved shoulders provided beneath the slot portions toengage the curved portion of the plates which form the stationary jaw,and said movable jaw may be moved to either side of the enlarged head ofthe handle.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts. to behereinafter fully described illustrated in the accompanying drawings andspecifically pointed out in the appended claim.

In describing my invention in detail ref erence will be had to theaccompanying drawin s wherein like characters of reference denote likeor corresponding parts in the several views, and in which Figure l is aside elevation of the inven tion.

Figure 2 is a front view thereof.

Figure 3 is a top plan view.

Figure 4: is a sectional view showing the relation of the toothed headwith the slidable jaw.

Referring now to the drawings wherein like characters of referencedenote like or corresponding parts 1 indicates a handle having anenlarged arcuate shaped head 2 which has spaced transverse teeth 3formed on the periphery thereof and an opening a formed centrally ofsaid head. A stationary jaw 5 consisting of a pair of spacedsubstantially T-shaped plates 6 which are pivotally connected togetheras at 7 by means of a pivot pin 8 which passes through openings 9 formedin the plates and through i the opening formed in the head. A movablejaw 10 has an extension 11 formed integrally therewith which has spacedtransverse teeth 12 provided on the under face thereof, said movable jawhas slots 13 formed on each side thereof to receive the plates formingthe stationary jaw. A curved shoulder 14 is formed on each side of themovable jaw directly beneath the slotted portion thereof and is adaptedto engage the curved portion 14 of the plates forming the stationaryjaw. The movable jaw may be moved transversely of the enlarged head toeither side thereof for gripping and tightening an object.

From the above it will be seen that when the user of the device wishestogrip and tighten an object he adjusts the movable jaw with respect tothe stationary jaw to fit such object and oscillates the handle of thewrench in either direction desired, that is, in the direction necessaryfor tightening an object.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of they several parts, providedthat such changes fall within the scope of the appended claim.

What I claim is A wrench of the character described comprising anenlarged arcuate shaped head formed on the handle thereof, a pair ofspaced cooperating substantially T-shaped plates providing a jaw andbeing pivotally secured at one end upon the opposite sides of the head,a curved portion formed on one side wall OI each T-shaped plate at thejuncture of their respective portions, a slidable jaw member having agroove formed on each side wall thereof for slidably receiving a portionof the plates, a curved shoulder formed in the lower wall of each groovefor operative engagement with the curved portion of the plates wherebyclose association ofthe slidable jaw with the first mentioned jaws isprovided and a toothed extension formed on the slidable jaw foroperative engagement with the teeth of the head.

In testimony whereof I afiix my signature.

CLAUD E. QUIER.
